Chromaticism
Encyclopedia
Chromaticism is a compositional technique interspersing the primary diatonic pitches and chords with other pitches of the chromatic scale. Chromaticism is in contrast or addition to tonality
Tonality
Tonality is a system of music in which specific hierarchical pitch relationships are based on a key "center", or tonic. The term tonalité originated with Alexandre-Étienne Choron and was borrowed by François-Joseph Fétis in 1840...

 or diatonicism (the major and minor scales). Chromatic elements are considered, "elaborations of or substitutions for diatonic scale members."

Tristan und Isolde is an opera, or music drama, in three acts by Richard Wagner to a German libretto by the composer, based largely on the romance by Gottfried von Straßburg. It was composed between 1857 and 1859 and premiered in Munich on 10 June 1865 with Hans von Bülow conducting...

    Tonicization
    In music, tonicization is the treatment of a pitch other than the overall tonic as a temporary tonic in a composition. Tonicization is achieved through the use of the scale and harmonies of the tonicized key. The most common method of tonicization uses leading tones, dominant-tonic chord...

As tonal harmony continued to widen and even break down, the chromatic scale became the basis of modern music written using the twelve tone technique, a tone row
Tone row
In music, a tone row or note row , also series and set, refers to a non-repetitive ordering of a set of pitch-classes, typically of the twelve notes in musical set theory of the chromatic scale, though both larger and smaller sets are sometimes found.-History and usage:Tone rows are the basis of...

. Though these styles/methods continue to (re)incorporate tonality or tonal elements, often the trends which led to these methods were abandoned, such as modulation.

    In music, the subdominant is the technical name for the fourth tonal degree of the diatonic scale. It is so called because it is the same distance "below" the tonic as the dominant is above the tonic - in other words, the tonic is the dominant of the subdominant. It is also the note immediately...

Chromatic note

A chromatic note is one which does not belong to the scale of the key prevailing at the time. Similarly, a chromatic chord is one which includes one or more such notes.

A chromatic scale is one which proceeds entirely by semitones, so dividing the octave

Key (music)
In music theory, the term key is used in many different and sometimes contradictory ways. A common use is to speak of music as being "in" a specific key, such as in the key of C major or in the key of F-sharp. Sometimes the terms "major" or "minor" are appended, as in the key of A minor or in the...

. In other words, at least one note of the chord is chromatically altered. Any chord that is not chromatic is a diatonic chord.

For example, in the key of C major, the following chords (all diatonic) are naturally built on each degree of the scale:
  • I = C major triad [contains notes C E G]
  • ii = D minor triad [contains D F A]
  • iii = E minor triad [contains E G B]
  • IV = F major triad [contains F A C]
  • V = G major triad [contains G B D]
  • vi = A minor triad [contains A C E]
  • vii = B diminished triad [contains B D F]


However, a number of other chords may also be built on the degrees of the scale, and some of these are chromatic. Examples:II in first inversion is called the Neapolitan
